Where to start about Embedded System
Where to start about embedded system ? The question is not clear! “Where to start learning embedded system development” might be the right question! For those embedded system enthusiasts! And for system integrators, most probably, “where to start using embedded system” is the correct question!
If some one wants to start learning how to develop embedded system, he must start with micro controllers and data sheet and than application notes.
Micro Controllers:
If one does not know about micro controllers yet, then most probably, he is reading the wrong article in wrong blog. Blame Google or Yahoo for landing you here!
For beginners, MCU(Micro Controller Unit) is complete computer on chip! Yes, that is true! MCU is capable of executing assembly language instructions on its own, and it has RAM, Program Storage memory ( Hard Disk Drive, you may call), input/output devices like RS232 ( COM port) etc. inbuilt into it! There are many MCU manufacturers! I would list out in future! ATMEL, Microchip, Philips are to name a few! My personal favorite still is ATMEL.
Data Sheet:
Data sheet is the document describing about the MCU! Normally it is available for downloading in the website of the MCU manufacturer. For example, if you want to download datasheet of ATMEL MCU, you need to visit ATMEL website ( Use Google or Yahoo to search ), head on to download section! Without reading data sheet of the MCU, one should not attempt to anything about embedded system using that MCU.
Application Notes:
As the name suggests, Application Notes are example documents how to use the MCU!
So the bottom line is, on internet, you get everything to start learning how to develop a embedded system product.
This article was just an introduction.
